Explains the different methods of Sampling with diagram. In statistics, quality assurance, and survey methodology, sampling is the selection of a subset of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt for the samples to represent the population in question.
Sampling and different ways of sampling under public opinion and survey research.Advantages and disadvantages of different sampling methods with pictures and examples.
Sampling means selecting the group that researcher will actually collect data from in research. It attempts to collect samples that are representative of the population.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. Basic Terminologies
Population
Sample and Sampling
Advantages & Disadvantages of
Sampling
Non-Probability Sampling
3. Population or Universe: The group of
people, items or units under investigation
and includes every individual.
Sample: A collection consisting of a part or
SUBSET of the objects or individuals of population
which is selected for the purpose, representing the
population
Sampling: It is the process of selecting a sample
from the population. For this population is divided
into a number of parts called Sampling Units.
4.
5.
6. Large population can be conveniently
covered.
Time, money and energy is saved.
Helpful when units of area are
homogenous.
Used when percent accuracy is not
acquired.
Used when the data is unlimited.
7. Economical: Reduce the cost compare to entire
population.
Increased speed: Collection of data, analysis and
Interpretation of data etc take less time than the
population.
Accuracy: Due to limited area of coverage,
completeness and accuracy is possible.
Rapport: Better rapport is established with the
respondents, which helps in validity and reliability of
the results
8. Biasedness: Chances of biased selection leading
to incorrect conclusion
Selection of true representative sample:
Sometimes it is difficult to select the right
representative sample
Need for specialized knowledge: The researcher
needs knowledge, training and experience in
sampling technique, statistical analysis and
calculation of probable error
Impossibility of sampling: Sometimes population is
too small or too heterogeneous to select a
representative sample.
9. A true representative of the population.
Free from error due to bias.
Adequate in size for being reliable.
Units of sample should be independent and
relevant
Units of sample should be complete precise
and up to date
Free from random sampling error
Avoiding substituting the original sample for
convenience.

11. 1. Probability Sampling: A probability sample
is one in which each member of the
population has an equal chance of being
selected.
2. Non-Probability Sampling: Nonprobability
Sample a particular member of the
population being chosen is unknown.
In probability sampling, randomness is the
element of control. In Non-probability
sampling, it relies on personal judgment.
12.
13. 1. Purposive Sampling: Researcher selects a
"typical group" of individuals who might
represent the larger population and then collects
data from this group. Also known as Judgmental
Sampling.
14. 2. Convenience Sampling : Obtaining units or
members who are most conveniently
available. It consists of units which are
obtained because cases are readily available.
Researcher determines the required sample size
and then simply collects data on that number of
individuals who are available easily.
15. 3. Quota Sampling: The selection of the sample is
made by the researcher, who decides the quotas
for selecting sample from specified sub groups of
the population.
For example, an interviewer might be needed data
from 40 adults and 20 adolescents in order to study
students’ television viewing habits.
Selection will be
20 Adult men and 20 adult women
10 adolescent girls and 10 adolescent boys
16. 4. Snowball Sampling:
In snowball sampling, the researcher
Identifying and selecting available
respondents who meet the criteria for
inclusion.
After the data have been collected from the
subject, the researcher asks for a referral of
other individuals, who would also meet the
criteria and represent the population of
concern.
